Drowning concerns

[kron4me]

I am in the process of building my first PDF vivarium, I am including a nice water fall and pool but my concerns are the frogs drowning. I want to have some aquatic plants so I would like to have 3 inches of water, is that a danger to the frogs? How deep can I make the water and it still be safe? Any help is appreciated!

I have three inches of water in my viv. I planted three types of anubias and some brazilian swords (all of which I grew emersed for four weeks prior) in the water, and added a stone that sticks well above the waterline. The main idea is to have a couple of areas where the dart frogs can get out of the water. Just do what you thinks looks good. It can be rocks, moss-covered logs, or plants. You could even slope the substrate all the way to the top on one end or whatever, just as long as the frogs can pull themselves out.

I have a little rocky beach, looks good and works, (I guess) no drownings yet. shallow water tho. they can't tread water at all
